CHAPTER 1: COMMUNICATIONS Adapter 25-Pin Male Connector TXD RXD Signal Ground DTR 2 3 7 20 9-Pin Female Connector 3 2 5 4 TXD RXD Signal Ground DTR SOI-to-PLC Communications Cable Requirements For communications, a SIMATIC S5 programmable controller contains a single programming port (which may also be used for point-to-point communications, as supported by the S5 protocol). The programming port is a female 15-pin D-sub connector configured as a serial digital 20 mA current loop interface.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE Note If an odd number of characters is received from the scanner, a Null character is added to create an even byte count. This facilitates word writes to the controller. If keypad entry is enabled, the operator may also enter the decimal equivalent of an ASCII character in the data entry field. For example, an operator can manually enter 2 characters and then scan a bar code containing 8 characters. The SOI then writes all 10 characters to the controller.
CHAPTER 2: PROGRAMMING CHAPTER 2: PROGRAMMING This chapter of the Siemens (S5 Communications) Reference addresses supported PLC registers and data formats, screen types and definitions, and PLC-specific configuration requirements.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE The S5 operands listed above can be addressed as bits, words, or bytes (exception: Timers and Counters are addressed as bits or words). Input Word 0, for example, would contain Input Bytes 0 and 1. Input Word 1 would contain Input Bytes 1 and 2. To address a word, the IW, QW, FW, T, C, and DW ID codes are used. To address a byte, the IB, QB, FY, DL (Data Word Left), and DR (Data Word Right) codes are used.
CHAPTER 2: PROGRAMMING Bit (KM) Bit Data MSB 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 LSB 16 individual bits (One 16-bit location) The PLC stores a binary (0 or 1) status for a bit location. The SOI will read a PLC bit location and determine whether the operational status of the bit is ON (1) or OFF (0). You can specify associated text to be displayed for either state of a specified bit. This description can be up to twenty characters.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE 16-Bit Signed Integer (Fixed Point, KF) 16-Bit Signed Integer MSB 15-Bit Data Field LSB Bit 15 (sign bit) Bit 0 Range = -32768 to +32767 This data type displays a 16-bit register as a signed Integer (two’s complement) value. The 16th bit of the register is the sign bit and is set (1) for a negative and cleared (0) for a positive number. The 16-bit signed integer values have a range of -32768 to +32767.
CHAPTER 2: PROGRAMMING This data type displays a 16-bit register location as a 4-digit Binary Coded Decimal value. The range for the 16 bit BCD selection is 0 to +9999. Note: This data format may also be scaled to different engineering units. 16-Bit Hexadecimal (KH) 16-Bit HEX MSB Digit 4 Bit 15 Digit 3 Bit 12 Bit 11 Digit 2 Bit 8 Bit 7 Digit 1 Bit 4 Bit 3 Bit 0 LSB Range = 0 to FFFF This data type displays a 16-bit register location as a 4-digit hexadecimal value.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE 32-Bit Binary Coded Decimal (KH) 32-Bit BCD MSB 16-Bit Location #1 16-Bit Location #2 (next sequential location) LSB Range = 0 to 99,999,999 This data type displays two consecutive 16-bit register locations as a 32bit BCD value. It uses a memory register plus the next higher register to form the 32 bit location. The range for the 32 bit BCD value is 0 to +99,999,999. Note: This data format may not be scaled to different engineering units.
CHAPTER 2: PROGRAMMING Each 16-bit location may contain two ASCII characters (1 byte each). By default, the most significant byte of the base address stores the first character, the least significant byte stores the second character, the first byte of the next sequential location stores the third character, and so on. The data held in this range of address locations is expected to be an ASCII data format.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE Screen Types and Data Formats Each SOI Screen type may not support all data formats. The following lists each screen type and the associated data formats supported.
CHAPTER 2: PROGRAMMING Data Display and Entry Screen Definitions When programming Data Display and Data Entry fields and positioning them on the SOI display, each field must be defined according to its PLC location, data format, and other data parameters specific to the data format selected. You are prompted for the register definitions at the Control Window.

CHAPTER 3: TROUBLESHOOTING CHAPTER 3: TROUBLESHOOTING This chapter of the Siemens (S5 Communications) Reference provides solutions to possible operational problems with the SOI and its use with the Siemens S5 processor. Also contained is a description of the Communication Error Codes specific to the S5 communication protocol used for the S5 processor and the SOI.
SIEMENS (S5 COMMUNICATIONS ) REFERENCE The following indicates PLC-oriented problems displayed on the SOI and possible actions to take if necessary. S5 PROTOCOL Establishing COMM Attempting to communicate to PLC This is the normal display when initiating communications with the PLC. S5 PROTOCOL This is displayed after a 4-second interval of attempting to establish communications with the PLC. Check cabling and communications parameters to verify that the PLC matches those of the SOI.
CHAPTER 3: TROUBLESHOOTING Error Code Description 12H, 15H, 16H General Message Structure Error An expected message response from the PLC did not occur. For example, an error would occur if the SOI expected but did not receive an acknowledge from the PLC of data written to the PLC. 14H Illegal Data Block The SOI requested a data block that is undefined within the PLC. The operator should request data from a data block that has been defined by the programming of the PLC.
